 						tool is still relatively soft, so changes can easily be made. If they need to remove material, they simply grind
 						it off. If they need to add material, they weld it on and then grind it off.

+						This is an annotated version of the case. You can see three major problems here: flow lines,
+						where the plastic partially cooled as it was still moving. Knit lines are where two rivers of molten plastic
+						meet. And sink marks, where not enough plastic flowed, and features on the inside can be seen through on the
+						other side. The factory will tune the mold and the flow rate to address these issues.
